CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority from U.S. provisional patent application No. 61/292,316, filed on Jan. 5, 2010, and which is incorporated by reference in its entirety, for all purposes, herein.

FIELD

The present disclosure relates to portable electronic devices, and more particularly to a method of remotely controlling a presentation to freeze an image using a portable electronic device.

BACKGROUND

Electronic slide presentations are a common way to display information to one or more viewers. Slide presentation software (e.g. PowerPoint®) facilitates the creation of multimedia documents that may incorporate text, images, audio and/or visual clips for presentation in one or more slides. Often the documents are presented in a slideshow, displaying the slides sequentially. The slides may be displayed to a display screen of a computing device (e.g. personal computer or portable electronic devices) or remotely via a presentation device such as a projector for projecting the presentation to a remote screen.

When displayed on a portable electronic devices such as wireless mobile devices (cellular phones, PDAs, etc.) a viewer may be provided for displaying slide presentations in multiple display modes, such as a text mode for displaying text information distilled from the slides, a preview mode for displaying thumbnail slide images rendered from the slides, and a mixed mode for displaying both text information and thumbnail slide images together. The slide presentation viewer may also include a slide show mode for displaying the slide images in full screen along with an interface (e.g. menu) for selecting among the multiple modes and for invoking and controlling the slide show. For handheld wireless communication devices in particular, a network server may process slide presentation documents to generate the text information and slide images for communicating to wireless devices equipped with appropriate slide presentation viewers. The network server may be an attachment server for handling email attachments and the slide presentation viewers may be implemented as attachment viewers for email or as dedicated viewers for presentations.

Portable electronic devices may also be capable of remotely controlling display of an electronic slide presentation. For example, a presentation mode of operation may be provided for wirelessly controlling display of a slide presentation on a remote presentation device. When controlling a presentation in this fashion, the slides being displayed on the portable electronic device are the same as those displayed on the presentation device. Therefore, it is not possible to view other slides on the portable electronic device without exiting the presentation mode, which causes the presentation device to show a blank screen and thereby interrupt the flow of the presentation.

DETAILED DESCRIPTION

As set forth in greater detail below, a system and method are set forth for remotely controlling a presentation from a portable electronic device so as to freeze a slide/page on a remote presentation device (e.g. projector), for example in order to permit searching for a desired slide/page on the portable electronic device, and then continuing the presentation when searching is complete. In one embodiment, a switch is provided in a communication layer of a presentation application such that when the switch is turned off, communication is suspended between the portable electronic device and the remote presentation device, thereby permitting browsing on the portable electronic device without interrupting the presentation. When the switch is turned on the current slide information is transmitted from the portable electronic device to the remote presentation device.

In one aspect there is provided a method of remotely controlling a presentation device from a portable electronic device, the method comprising: establishing communication between the portable electronic device and presentation device; sending presentation data and commands from the portable electronic device to the presentation device so that a presentation is displayed simultaneously at the portable electronic device and presentation device; suspending said commands while permitting at least one of navigation through and manipulation of said presentation at said portable electronic device; and resuming said commands for continuing display of said presentation simultaneously at the portable electronic device and the presentation device.

In another aspect there is provided a presentation system, comprising: a portable electronic device capable of displaying a presentation; a presentation device; a communications component in each of said portable electronic device and presentation device for establishing communication therebetween; a presentation application component associated with the portable electronic device in communication with a presentation adapter associated with the presentation device via each said communications component for sending presentation data from the portable electronic device to the presentation device so that said presentation is displayed simultaneously at the portable electronic device and presentation device and for remotely controlling the display of said presentation data at the presentation device, including suspending remote control by the portable electronic device and freezing the presentation at current slide being displayed simultaneously at the portable electronic device and the presentation device so as to enable navigation between other slides at said portable electronic device, and resuming remote control of the presentation device by the portable electronic device at a current slide being displayed on the portable electronic device.

The term “slide” as used throughout the specification and drawings includes, but is not limited to, a single presentation slide (such as a PowerPoint® slide), a page in a PDF document, or a single photo image.

FIG. 1 shows a communication network system 100 comprising at least one portable electronic device 112, a public IP network 114 (including a wireless carrier network and base station (not shown)), a wireless network gateway server 116, an enterprise email server 117, an enterprise wireless communication device server or proxy server 118 and an attachment server 119.

Portable electronic device 112 is operable to effect communications over public IP network 114 via a radio communications channel, and communicates with the base station (not shown) while located within a coverage area that is defined by the base station. The base station is part of the wireless public IP network 114, or other network such as a WAN. Data is delivered to the portable electronic device 112 via wireless transmission from the base station. Similarly, data is sent from the portable electronic device 112 via wireless transmission to the base station.

It will be appreciated that the portable electronic device 112 is movable within the coverage area and can be moved to coverage areas defined by other base stations. Further, as will be understood by one of ordinary skill in the art, wireless networks include GSM/GPRS, CDPD, TDMA, iDEN, Mobitex, DataTAC, EDGE, EVDO or UMTS and broadband networks such as Bluetooth™ (as originally standardized by IEEE (Institute of Electrical and Electronics Engineers) 802.15.1)and variants of 802.11.

Portable electronic device 112 is further operable to deliver content to and control a remote presentation device 113. For example, device 112 can send slide presentation content and control signals to the presentation device 113 for controlling the display of a presentation, such as a PowerPoint® presentation or successive pages of an image attachment, such as a PDF document.

Proxy server 118 handles client requests from portable electronic device 112 for documents stored within attachment server 119. The attachment server 119 communicates with the proxy server 118 to transmit attachments such as documents, spreadsheets, images, multimedia files, etc. through the gateway 116 and network 114 for viewing via an attachment viewer of the portable electronic device 112 so as to allow a user to view attachments that are received in email messages. While only one attachment server 119 is shown for illustration purposes, a person skilled in the art will understand that the attachment server 119 may alternatively be a network of attachment servers. Sources for the attachments stored within server 119 may include mail server 117, and may include a web server, IM server, etc. Preferably the attachment data is downloaded to portable electronic device 112 in chunks of binary data in an attachment viewer readable format, for example Universal Content Stream (UCS) format.

Referring now to FIG. 2, a block diagram of certain components within the portable electronic device 112 is provided. In the present embodiment, the portable electronic device 112 is based on the computing environment and functionality of a wireless communications device incorporating personal digital assistant (PDA) functionality. It will be understood, however, that the portable electronic device 112 is not limited to wireless communication devices. Other portable electronic devices are possible, such as smart telephones, portable multimedia players and laptop computers.

The portable electronic device 112 includes a processor 200 connected to a read-only-memory (ROM) 210 that contains a plurality of applications executable by the processor 200 for enabling the portable electronic device 112 to perform certain functions including, for example, PIN message functions, SMS message functions and cellular telephone functions, and at least one attachment viewer application for viewing attachments (e.g. document attachments to emails or documents from other sources, such as web servers, etc.). The processor 200 is also connected to a random access memory unit (RAM) 220 and a persistent storage device 230, which are responsible for various storage functions of the portable electronic device 112. The processor 200 receives signals from input devices such as a keypad 240, trackball and/or touch sensitive input 250. The processor 200 outputs signals to various output devices, such as LCD display 260. A microphone 270 and phone speaker 280 are connected to the processor 200 for cellular telephone functions. The processor 200 is also connected to a modem and radio device 290. The modem and radio device 290 is used to connect to wireless networks for transmitting and receiving voice and data communications through an antenna 294. A Bluetooth™ receiver/transmitter 296 may be provided to effect wireless (i.e. infrared) communication between device 112 and other Bluetooth™-enabled devices, such as presentation device 113, as discussed in greater detail below. A content store 298, which is generally a file storage system for the portable electronic device 112, may also be provided.

Request/view functionality for an attachment is provided by the client/server combination of the attachment viewer within portable electronic device 112 and the attachment server 119. More particularly, with reference to FIG. 3, portable electronic device 112 is configured (e.g. via software stored, for example, in ROM 210) to comprise various components including an operating system 300, a communications system 305 for wireless communication, an email application 310 and other applications 315. Email application 310 may comprise or otherwise cooperate with various attachment viewers 320 for retrieving and viewing attachments. One such attachment viewer is slide presentation viewer 325. Other viewers 330 may include spreadsheet viewers, image viewers, word processing document viewers, etc. (not described herein). Other applications 315 may include communication and control applications 317 and a presentation application 319 for communicating with and controlling presentation device 113.

Attachment server 119 is configured (e.g. via software stored, for example, in non-volatile memory (not shown)) to include various components including an operating system 335, communications system 340, slide presentation attachment handler 345 as well as other attachment handlers 347 for other attachment types. Slide presentation attachment handler 345 comprises or otherwise cooperates with a text distiller 350 and slide renderer 355. Text distiller 350 is configured to parse or otherwise review slide presentation documents to extract text information for delivery to handheld devices such as portable electronic device 112. Slide renderer 355 defines rasterized slide images (e.g. in a jpeg, tiff or other image format) from the slide presentation document for each slide.

The attachment server 119 and/or proxy server 118 and portable electronic device 112 communicate such that when a user invokes the attachment viewer 325 to view the content of a slide presentation, the portable electronic device 112 transmits one or more requests for slide information, (i.e. the text information and slide images) and receives the requested slide information in response. Requests and responses are illustrated notionally as communicating directly between the portable electronic device 112 and attachment server 119 but it is understood that communications may be through network 114 via gateway 116 and proxy server 118.

Due at least in part to communication protocol constraints on the size of a message, a single message may be insufficient to communicate all of the text information and/or all of the slide images required for a slide presentation document. Thus, the portable electronic device 112 may make multiple requests either automatically or in response to direct or indirect user actions. For example, during a slide show, the slide presentation viewer 325 may automatically make requests for slide information in the background while a slide show is being viewed. To that end, the viewer 325 may anticipate the need for more slide information in response to an input via trackball or touch input 250 scrolling toward the end of the slide presentation on the portable electronic device 112. Alternatively, a menu choice may be invoked (e.g. a “More” command) for additional slide information, as applicable, to pre-load slides.

Preferably, a request (e.g. for slide information) includes a flag or other data indicating a screen size of the screen 260 when rendering slide images. This may be a specific pixel size (e.g. 340×280), a code flag (1=340×280 pixels) or a device type, among other information, where the attachment server 119 or proxy server 118 determines the screen size from the code flag or device type. Other display capabilities may be indicated to the attachment server 119 as well or alternatively. For example, the colour capabilities of the display screen (e.g. black and white only or the number of colours available), reflective type, etc. may be indicated to help render slide images. The attachment server 119 may then adjust the colour palette of the rendered slide presentation for viewing on the requesting device 112.

Slide presentation viewer 325 provides a graphical user interface (GUI), described in greater detail below, to present the slides in the various modes and provides a menu or other command interface for user input to invoke the presentation application 319 for transmitting the slide presentation to remote presentation device 113 and controlling the presentation thereat.

More particularly, according to one embodiment, presentation device 113 may include a presentation adapter 360 for communicating with presentation application 319 so that the presentation application 319 may remotely freeze an image on the presentation device 113 so that other slides may be viewed on portable electronic device 112 without exiting the presentation mode and causing the presentation device to show a blank screen.

In addition to presentation adapter 360, presentation device 113 may include other hardware and/or software such as communications 365, other projector applications 370 and an operating system 375.

With reference to FIG. 4, a method is set forth for downloading and viewing a presentation on portable electronic device 112, using the functional components of FIG. 3. First, at 400, the portable electronic device 112 requests an attachment (e.g. slide presentation) from attachment server 119. The request may be initiated, for example, by a trackpad, touch screen or trackball click or menu item selection to “Open attachment” or “Download attachment”. The presentation attachment may be an attachment to an email, calendar event, instant message (IM), browser link, or other attachment-enabled event.

Alternatively, if the presentation attachment has been previously saved to memory of the device 119 (e.g. persistent store 230 or SD card (not shown)), then the attachment is locally retrieved and process flow continues at FIG. 5.

If the presentation attachment has not been previously requested (i.e. a “No” at 410), attachment server 119 builds a Document Object Model (DOM) that represents the attachment by parsing the attachment document (step 420). In this manner, a graph structure is built within attachment server 119 representing a map of the original attachment file. The DOM contains textual content, font, style and formatting attributes as well as layout attributes, such as page/slide size, positioning information (i.e. x, y and z coordinates on the page), embedded graphics and tables, for example. DOM structure is known and is disclosed in United States Patent Application No. 2006/0055693, which is incorporated herein by reference.

Once the DOM of the attachment has been built the attachment server 119 transcerpts and encapsulates the DOM in UCS data, as indicated at 430. The UCS data is then sent to portable electronic device 112 in chunks, as indicated at 440. Each chunk is a self-contained data representation of a portion of the presentation attachment (e.g. one slide of a presentation). That is, there is sufficient data contained in a chunk to enable the attachment viewer to display the content of the chunk. Depending on the size of the chunks and the size of the attachment, the entire attachment can be transmitted in one chunk or in multiple chunks. Depending on the nature of the request from the attachment viewer, attachment server 119 can transmit the chunks in sequence or out of sequence. For example, if the attachment viewer requests the fifth slide of a presentation attachment, attachment server 119 can transmit the chunks corresponding to the fifth slide, even if chunks for the first through fourth slides have not been transmitted to portable electronic device 112.

The attachment is then previewed via display 260 and several menu or command options are made available at step 450, such as “Present”, “Retrieve Info/View Info”, “Zoom”, “Rotate”, “Fit to Screen”, “Next Slide”, “Save Slide”, “Download Attachment”, “Help”, “Call Voice Mail”, etc. Additional operations may be performed in response to actuation of the trackball/touch input device 250, such as scrolling to a next (or previous) slide.

Upon selection of the “Present” command (step 500), the presentation application 319 is launched, as shown in FIG. 5. At step 510, the application first checks to see that the presentation adapter 360 is connected. If not, a communication channel is established between portable electronic device 112 and remote presentation device 113 via a pairing connection process (step 515). The pairing connection process may call up a “wizard” for presenting steps to establish communication pairing between portable electronic device 112 and presentation adapter 360 of presentation device 113 using communications applications 305 and 365 (e.g. Bluetooth discovery and pairing).

Upon selection of the “Present” command (step 500), the presentation application 319 is launched, as shown in FIG. 5. At step 510, the application first checks to see that the presentation adapter 360 is connected. If not, a communication channel is established between portable electronic device 112 and remote presentation device 113 via a pairing connection process (step 515). The pairing connection process may call up a “wizard” for presenting steps to establish communication pairing between the device 112 and presentation adapter 360 of the presentation device 113 using the communications applications 305 and 365 (e.g. Bluetooth™ discovery and pairing).

At step 520, application 319 sends at least one of a slide number and animation sequence number to the paired presentation adapter 360. The application then checks for slide presentation data (e.g. a first UCS chunk representing the first slide) having already been transmitted to and locally stored at the presentation adapter 360 (step 525). If not, the presentation application 319 sends the slide data to presentation adapter 360 (and simultaneously requests additional data from the attachment server 119, as discussed above in connection with FIG. 4).

At step 540, presentation application 319 sends a command to the presentation adapter 360 to display the first slide, while the first slide is simultaneously displayed on the portable electronic device 112 (e.g. functionally equivalent to that initiated by pressing “F5” on a PC in order to display a PowerPoint® presentation).

Turning to FIG. 6, the presentation typically starts from the first slide regardless of which slide was in preview at 450. Alternatively, an option may be provided for starting the presentation from the slide that is being previewed at 450.

When UCS slide data is being transmitted to the presentation adapter 360 (e.g. at step 530), the portable electronic device 112 must determine what to show on the display 260 (step 605). When displaying a PDF image or other non-presentation file format, the display 260 mirrors what is being displayed by the presentation device 113 through the presentation adapter 360 (step 610). When displaying a presentation (e.g. a .PPT file), and if no alternate presentation option has been selected (step 615) then if text is associated with a slide (step 620), the device 112 can display such text (e.g. speakers notes) while the slide is being displayed via presentation device 113 (step 625). On the other hand, if no such text exists then the portable electronic device 112 can display simple message, such as “Slide #______, No notes” for any slides that are not associated with content in the notes and the slides on the display 260 mirror what is being displayed via presentation device 113.

Additional display options may be provided (step 630), such as “Text”, which shows the slide text with images stripped out, “Slides” and “Both”, which shows a thumbnail image of the complete slide, above a larger display of text stripped out from that slide.

If there are no slides with speakers notes in the entire presentation, the presentation format can default to mirror the content of display 260 with the remote presentation device display, unless the user has previously chosen an alternate handheld display option (step 615).

A menu option may be provided to switch the content on the display 260. If such an alternate option is chosen, the new option may be selected as a new default the next time the presentation adapter 360 is launched.

As shown at step 635 and set forth in Table A, various presentation control options may be provided. The menu options include several basic control options, which may be implemented differently depending on whether they are actuated from a menu button on device 112, trackball/touch input 250, or a keyboard short-cut on keypad 240. Preferably, a “tool tip” is displayed via display 260 during navigation between slides, for showing at least the slide number, and title of the slide.

User entered setting becomes the new default. Ending a looped presentation - see notes. End Show “End Show” Msg box should pop-up asking user “Are you sure you want to exit”

Three methods are briefly described for ceasing control of a presentation: (i) Losing the Bluetooth™ (BT) connection (step 640), for example as a result of moving out of range of the presentation adapter 360), and deliberate closing of the presentation (step 645) by (ii) ending the session at the presentation adapter 360, or (iii) closing the presentation via the presentation application (319).

If the Bluetooth™ connection is lost during the presentation (step 640), the portable electronic device 112 preferably vibrates and displays a “connection lost” message or provides some other indication of the lost connection, and an “Active Session Recovery” process (step 650) is invoked to try and recover the connection using a previously established session ID (520).

If the option to end the presentation is deliberately selected (step 645), the presentation adapter 360 closes, thereby returning the presentation device display to its state previous to opening the presentation (step 655) and the wireless pairing between device 112 and presentation device 113 is broken.

Turning now to FIG. 7, a method is shown for remotely controlling the presentation to freeze an image, according to an embodiment. At step 700, a menu item is selected at portable electronic device 112 to “Freeze” the presentation (e.g. via manipulation and/or actuation of one or more of trackball/touch input 250, keypad 240, etc.) Presentation application 319 causes an advisory message or icon to be displayed via display 260 (step 710) to indicate that presentation control inputs at the device 112 are no longer being communicated to the presentation adapter 360 for remote control of the presentation at presentation device 113, and further presentation commands from the portable electronic device 112 to the presentation device 113 are suspended (step 720) so that the current slide continues to be displayed via presentation device 113. Menu or other control inputs may then be processed at the portable electronic device 112 as discussed above in connection with reference 450 of FIG. 4, to navigate (e.g. jump) to a desired slide or otherwise manipulate the presentation (e.g. delete slide, edit slide, etc.) Upon selection of a menu item at portable electronic device 112 (step 730) to “Unfreeze” the presentation (e.g. via manipulation and/or actuation of one or more of trackball/touch input 250, keypad 240, etc.), further presentation commands from the portable electronic device 112 to the presentation device 113 are resumed (step 740) so that the desired slide is displayed via presentation device 113, and the advisory message is cancelled (step 750).

Turning now to FIG. 8, an alternative method is shown for remotely controlling the presentation to freeze an image, according to an embodiment. At step 800, a menu item is selected at portable electronic device 112 to “Go to . . . ” a particular slide in the presentation. Presentation application 319 generates an icon to indicate the “frozen” status” or, alternatively watermarks the current slide as a background image, and presents a thumbnail image of the slide at display 260. Further presentation commands from the portable electronic device 112 to the presentation device 113 are suspended (step 820) so that the current slide continues to be displayed via presentation device 113. Menu or other control inputs may then be processed at the portable electronic device 112 as discussed above in connection with reference to step 450 of FIG. 4, to navigate (e.g. jump) to a desired slide or otherwise manipulate the presentation (e.g. delete slide, edit slide, etc.). If, at step 830, the desired slide is selected (e.g. by actuating (i.e. clicking) the trackball/touch input 250 on the thumbnail image of the desired slide), further presentation commands from the portable electronic device 112 to the presentation device 113 are resumed (step 840) so that the desired slide is displayed via presentation device 113. The presentation then resumes. Otherwise, if no image has been selected at step 830 and an escape key (or other input) has been actuated on the portable electronic device 112 (step 840) then the presentation resumes on both the portable electronic device 112 and the presentation device 113 at the frozen slide.

A specific embodiment has been shown and described herein. However, modifications and variations may occur to those skilled in the art. For example, one or more of the functional components of the presentation device 113, such as presentation adapter 360, may be incorporated into the device 113 or may be implemented in a separate interface or control device that is connect to the presentation device 113. All such modifications and variations are believed to be within the sphere and scope of the present embodiment.
